Kevin Carter 11c7b27235 Add boot priorities to containers
This change adds boot priorities to some container types where it'd be
beneficial. LXC allows containers with higher priority values to be
started ahead of others. The container default is 0 and all integers
greater than 0 will be started in descending order.

This change has no upgrade impact as the additional config is only used
on boot and will not require a container to be restarted.

features:
- Container boot ordering has been implemented on container types
where it would be beneficial. This change ensures that stateful
systems running within a container are started ahead of
non-stateful systems. While this change has no impact on a running
deployment it will assist with faster recovery should any node
hosting container go down or simply need to be restarted.
- A new task has been added to the "os-lxc-container-setup.yml"
common-tasks file. This new task will allow for additional
configurations to be added without having to restart the
container. This change is helpful in cases where non-impacting
config needs to be added or updated to a running containers.
